STEAM-GENERATOR- Noi 823,230.,

Specification of Letters Patent.

Applicationfiled February 3. 1906. Serial No. 299,353,

To all whom it may concern;

Be it known that I, JAMES: C. SUYDAM, a citizen of the-United States,residing at Edenton, in the county of Ohowan and State, of North Carolina, have invented new and use- Improvements in Steam-Generators, of which the following is. a specification,

My invention ertains to steam-generators; and it contemp "ates the provision of a compact sectional generator susceptible of being easily repaired and constructed with a. View of quickly generating steam and withstanding the usage to which the steam-generators of motor-vehicles, fire-engines, and the like are ordinarily subjected.

With the foregoing in mind the invention will be fully understood from the following description and claims when the same are considered in connection with the accompanying drawings, forming-part of this specification, in which Figure 1 is a vertical section of the generator constituting the present embodiment of my invention with some of the parts in elevation; through the steam-chamber of the generator in the plane indicated by the line 2 2, of Fig. 1, and Fig. 3 is a horizontal section taken in the plane indicated by the line 3 3 of Fig. 1 looking downwardly. i

Similar letters designate corresponding arts in all of the views of the drawings, reerring to which A is the lower section of my novel generator, which is preferably, though not necessarily, circular in horizontal section and is designed to contain in its lower portion a firebox and a hydrocarbon-burner or any other suitable means for affording the heat necessary to generate steam. Such heat-affording means forms no part of my invention, and I have therefore deemed it unnecessary to illustrate the same.

The lower section A is provided with a door-opening a and a door I) to permit of access being readily gained to the heat-affording means, and said section is preferably made up of an inner wall 0, an outer wall d, connected by stay=bolts e to the-inner wall and extending slightly above said inner wall, as indicated by f, for a purpose presently set forth, and lower and upper rings 9 and h, interposed and secured between the walls 0 and d, so as to form an annular water-leg B. At the points shown in Figs. 1 and 3 the lower section A is provided with sleeves 7c, which Fig. 2 is a horizontal section taken extend through the inner and outer walls 0 and d and the water-leg B, and are designed tocarry or containpipes,presently described.

(1 is the upper section of the generator, in

vwhich the steam-chamber D is contained.

The said upper section C comprises a side wall or shell Z, lower and upper heads. m and n, flanged and riveted to the side wall or shell, the rivets complementary to the lower head having their outer heads countersunk, as shown in F ig, 1 for a purpose which will presently appear, and a plurality of flues p for smoke and other products of combustion, extending between and through both of the heads m and n and supporting and staying the same. The lower end of the upper section C'is set within the extended portion f of the lower section A, and packing r, of asbestos or other suitable material, is interposed between the two to prevent the escape of flames through thejoint. The two sectionsv A and Care detachably connected together by the opposed lugs s thereon and the bolts and nuts. At its upper end the upper section '0 is'equipped with a loop 15, preferably connected through stud-bolts, by which it may be lifted from the lower section A.

E is a stand-pipe carried by and depending from the lower head of the section 0. The said pipe is exteriorly threaded at u to engage the correspondingly-threaded opening 4) in the lower head of section C, and it is provided at its upper end with a threaded ring to, which is arranged on and connected to. the head m and is preferably, though not necessarily, provided with a plurality of radial apertures 00, registered with apertures :13 in the. stand-pipe and designed to conduct water from the interior of the standpipe and distribute such water over the lower head of the steam-chamber. The standpi e being threaded into. head m and the ring w heing in chamber D assures the joint being water and steam tight.

Extending longitudinally from the lower end of the stand-pipe E and through the center of said stand-plpe to the upper head n of the section C is a flue F, which is fixed to the stand-pipe and the upper head n and is open at its lower and upper ends, so as to assist in conveying the products of combustion from the combustion-chamber and utilizing the heat given off by such products to convert the water into steam. The flue F assists the flues p in supporting and lending strength to the heads m and n of section 0, as do also the stay-rods y, which are grouped about the flue F and are interposed between and connected to the lower and upper heads, as shown in Figs. 1 and 2.

G G are pipes arranged outside the sections A and O and connecting the water-leg B and the steam-chamber D. These pipes respectively comprise lower and upper sections and unions detachably connecting said sections, and hence it will be apparent that when the boiler is set up ready for use said pipes will assist inthe circulation of water from one section of the generator to the other, and yet when it is desired to separate the sections of the generator the sections of the pipes may be expeditiously and easily disconnected to permit of such separation.

H H are coils of pipe connected at their upper ends to the steam-chamber D and at their lower ends to the stand-pipe E in the manner shown in Fig. 1. These coils H are substantially of the same height as the standpipe E and are arranged in two (more or less) circular series, as illustrated, with a view of utilizing the heat given of]? by the products of combustion to the best advantage. The said coils H by virtue of their pendent position relative to the steam-chamber D are always occupied by water and permit 'lree circulation of water, and consequently it will be apparent that there is no liability of the said coils being burned notwithstanding their direct exposure to the fire.

I I, Fig. 3, are pipes for the circulation of water interposed between and connecting the lower portion of the stand-pipe E and portions of the water-leg B at opposite sides of the doorway a, and J and K, Figs. 1 and 3, are pipes connected to the lower portion of the stand-pipe E and extending through the before-described sleeves 7c and provided outside said sleeves with washers 2, designed to prevent the escape of flames and heat. The pipe J is provided at a point outside the section A with a cook a, designed. for use in re moving collected sediment from the standpipe E, and it is also provided at a, point between the cock a and the section A with a depending branch pipe I), which is connected at its lower end to a pipe 0, which in turn is connected to the water-leg B and is provided on its outer portion with a cock (1, designed to be opened when it is necessary to remove collected sediment from the water-leg. The pipe K is provided outside of the section A with a branch 6, which is connected to the water-leg B and is designed to be connected to an injector or other means (not shown) for supplying the generator with water.

From the foregoing description the general operation of my novel generator will be fully understood, and such operation need not, therefore, be entered into in detail. It will also be apparent from the foregoing that my novel generator is possessed of a large heatingsurface for the rapid generation of steam and is so constructed as to assure equal expansion of all of its parts. It will further be apparent that the capacity of the chamber D is sufficient to prevent rapid evaporation in the event of the water getting low and that by reason of the lower and upper sections being separable access may be readily gained to all of the interior parts to facilitate repair or replacing of the same.

While I have described the present embodiment of my invention in detail with a view of imparting a definite understanding of all of its parts, I desire it distinctly understood. that in practice such changes or modifications may be made as fairly fall within the scope of my invention as claimed. I also desire to make it plain that in practice the generator is designed to be arranged in a casing compatible with its proper operation. Such casing, however, forms no part of my invention, and I have therefore deemed it unnecessary to illustrate the same.
